The Padres activated Tatis (thigh) from the 60-day injured list Monday.
Tatis has been sidelined since late June with a stress reaction in his right femur. He had been working out at the team's spring training complex in Arizona the last several days and came out of it well enough that he'll skip a rehab assignment and go right back into the Padres' lineup. Tatis is starting in right field and batting second Monday versus the Tigers in his return to action.
